HA Sustainable Infrastructure Capital(HASI), a US-based infrastructure investment firm has closed a $ 500 million joint venture with Sunrun,  to finance distributed energy assets in the United States. The agreement, closed in December 2025, has been structured to support more than 300 MW of residential solar and storage capacity across over 40,000 home power systems. Under the arrangement, HASI Capital has provided structured equity that has monetised a portion of long-term customer cash flows, while Sunrun has retained a significant ownership interest in the underlying assets. According to HA Sustainable Infrastructure Capital, the structure has allowed flexibility in senior project debt. Sunrun said that the joint venture has been accounted for as a consolidated entity within its financial statements.
